BEDSPRING FABRIC.

Application filed December To all whom it may concern:

lie it known that I, SOLOMON CAHAN, a citizen of the United States, residing in New York, in the county of New York and State of New York, have invented certain new and useful Improvements in a Bedspring Fabric, of which the following is a specification.

The present invention relates to spring fabrics, and particularly to spring fabrics used in connection with beds, couches and other articles for reclining or sitting thereon, and one object is to provide a fabric of this character composed of longitudinal links and lateral or spacing links, the links being connected to form the fabric by engagement of hook portions of the links with indented or pocket portions of other links.

Another object is to provide a spring fabric of the character mentioned in which the links are of a form adapted to provide the requisite resiliency, together with increased bearing surfaces of the links for supporting the weight imposed thereupon.

Another object is to provide a spring fabric of the character mentioned composed of longitudinal links and lateral or spacing links cooperating therewith to form a fabric which will not lessen materially in width due to the weight imposed thereon.

l accomplish'these and suchothcr objects and advantages as may appear during the subjoincd description by way of example of one embodiment of the invention shown in the accompanying drawings. in which Figure 1 is a plan view of the spring fabric viewed from the under side thereof and shown broken longitudinally and transversely for convenience of illustration, and indicating that it is composed in width and length of a greater number of links than are shown in said viewr Fig. 2 is a sectional view of the spring fabric on the line 22 of Fig. 1;

Fig. 3 is a side elevation of a lateral or spacing link on an enlarged scale;

Fig. 4 is an end elevation of the link shown in Fig. 3; and

Fig. 5 is a detail view of a modified form of end connection.

Similar reference characters denote simi lar parts throughout the several views.

The spring fabric is shown in connection with a frame having side-pieces l0 and endpieces 11 and 12, but I do not restrict my- 19, 1922. Serial No. 607,839.

self to a frame of any particular form or construction.

The spring fabric comprises in its main parts or elements. the mid-links 13, the marginal links 1-1, the lateral or spacing links 15. the end-connecting mid-links 16 having yokes, the end-connecting marginal links 11' having: yokcs, the end-connecting; mid-links 18 having eyes. and the club connecting marginal links 19 having eyes.

The mid-links 13 are lengths of suitable wire. the wire being bent. at intermediate portions thereof to form yoke ends and parallel arms. the arms being of equal length. The yoke ends have inwardly extending portions 20 and indentations or pockets 21 which pockets are substantially semi-circular in configuration on each side of the extensions 20. the parallel arms terminating in books 22 arranged in planes transversely to the planes of the inward extensions 20. the purpose of the inward extensions 20 being: to space the indentations or pockets 21 apart and provide greater resiliency for the links and an increased amount of supporting surface of the links for the weight imposed thereon.

The marginal links 14 are similar to the mid-links 13 except that the marginal links are provided with parallel arms of unequal length, the shorter arms being" the same in length the parallel arms of the mid-links.

The lateral or spacing links 15 are lengths of wire, bent to form yokes of substantially elongated W-shapc. having inward extensions 23 with indentations '24 substantially semicircular in configuration on each side thereof. the ends or arms 25 of the yokes being extended substantially parallel to each other and parallel to the inward extensions 2 for the length of the inward extensions and bent to fori'n hooks 26, which lie in planes transversely to the planes of the inward extensions 23. the purpose of the extensions 23 being to space the indentations or pockets 24- apart and provide greater resiliency for the links and an increased amount of supporting surface of the links for the weight imposed thereon.

The endconnecting mid-links 16 and end connecting marginal links 17 are lengths of wire bent at intermediate portions to form yoke end similar to the yoke ends of the mid-links 13. having inward extensions 27 and indentations or pockets 28 substantially semicircular in configuration on each side thereof. The arms of the end-connect ing mid-links 16 and marginal links 17 converge from the yokes and at their converging ends are bent to form hooks 29 which lie in planes transversely to the planes of the yoke ends.

The end-connecting mid-links 18 and endconnecting marginal links 19 are lengths of wire bent at intermediate portions to form eyes 30. The arms of the end-connecting mid-links 18 and marginal links 19 diverge from the eyes 30 and at their diverging ends are bent to form hooks 31 which lie in planes transversely to the planes of the eyes 30.

F or connecting the end mid-links 16 and end marginal-links 17 to the end-piece 12, the mid and marginal resilient helix members 32 and 33 and mid and marginal rings 34 and are provided; and for connecting the end mid-links 18 and end marginallinks 19 to the end-piece 11. the mid and marginal resilient helix members 36 and 37 are provided.

The spring fabric when in assembled form consists of mid-links 13, marginal-links 14, end-connecting mid-links 16 and 18 and endconnecting marginal-links 17 and 19 arranged in connected relation to each other longitudinally of the frame and resiliently connected to the end-pieces thereof, and a plurality of series of lateral or spacing links 15 arranged transversely of the frame in connected relation to each other and to the mid-links 13. marginal-links l4, end-coni'iecting mid-links 16 and 18 and end-connecting marginaldinks 17 and 19.

In assembling the spring fabric mid resilient helix members 32 are connected by hooks at one end thereof to the end-pieces 12. the hooks of these helix ment ers engaging in interior spaced holes 38 arranged in the end-piece. the hooks at the opposite ends of the mid helix members being engaged with the mid rings 34. The marginal helix members 33 are connected by the books at one end thereof to the end-piece 12. the books of these helix members engaging in the marginal spaced holes 39 of the endpicce, the books at the opposite ends of the marginal helix members being engaged with the n'iarginal rings 35. The hooks 29 of the end-connecting mid-links 16 are engaged with the mid rings 34, and the books 29 of the end-connecting marginal-links 17 are engaged with the marginal rings 35.

In the transverse series of spacing links arranged in the line .r;r of Fig. 1, the inner spacing links 15 constitute interior spacing links and the outermost links 15 constitute marginal spacing links. The interior spac ing links 15 are connected to the end-connect ing midelinks 16 by engagement of the books 26 of the spacing links in the pockets 28 of the eml-ccnne t ne midJinks, the b s 26 of the outer arms of the marginal spacing links engaging the inner pockets 28 of the end-connecting marginal-links 17. The mid links 13 are connected to the interior spacing links 15 by engagement of the books 22 of the mid-links in the pockets 24 of the interior spacing links. The marginalslinks 14 are connected to the marginal spacing links 15 and to the end-connecting marginal-links 17 by engagement of the books 22 of the short arms of the marginal-links 14 in the outer pockets 24 of the marginal spacing links 15 and engagement of the hooks of the long arms of the marginal links 14 in the outer pockets 28 of the endconnecting marginal-links 17.

In the transverse series of spat'ting links arranged in the line 1 2 of Fig. 1, the interior spacing links 15 are connected to the mid-links 13 by engagement of the hook ends 26 of the interior spacing links in the pockets 21 of the mid-links, the marginal spacing links being connected to marginal-links 14 by engagement of the outer books 26 of the marginal spacing links in the inner pockets 21 of the marginal-links 14. The midlinks 13 next in progression are connected to the interior spacing links 15 by engagement of the books 22 of the mid-links 13 in the pockets of the interior spacing links, and the marginal-links 14 next in progression are connected to the marginal spacing links 15 and to the prior connected marginal spacing links 14 by engagement of the books 22 of the short arms of the marginal-links in the outer pockets 24 of the marginal spacing links and engagei'nent of the books 22 of the long arms of the marginal links 14 in the outer pockets 2] of the prior con-- nected marginal links 14. this arrangement of midlinks. marginal links and transverse spacing links being repeated progressi ely until the fabric extends longitudimilly to th mid-links 13 and marginal links I4 adj cent to the end-connecting mid and marginal links 18 and 19. The lastmentioned midlinks 13 and marginal links 14 are connected at their hook ends to the last prior series of spacing links in the. progression, and are connected at their yoke ends to the endconnecting mid and marginal links 18 and 19 by ei'igagemcnt of the books 31 thereof in the pockets 21 of the mid-links 13 and ma rgii'izzl links 14. The end-connecting mid-links is are connected to the end-piece 11 by engagement of the books at one end of the helix members 36 in the eyes 39 of the end-counecting mid-links and engagement of the books at the opposite ends of said members with the spaced holes 38 in the end-piece. the. mid-connecting marginal-links 19 being con nected in a similar manner to the end-piece 11 by the helix members 37 engaging in the spaced holes 39 of the end-piece.

For obviating the use of the rings 34 and 35, I provide endeonnecting mid-links and end-connecting Inarginal-links such as 1-0 shown in Fig. 5, having eyes 4]. and hook ends 42 arranged in the same plane, the eyes 41 being engageable with the hooks of helix members 32, and the hooks 1-2 being engageable with the hooks 2:2 of marginal links 14, and with the hooks of the spacing links 15.

It should be noted that as regards the supporting surfaces formed by the yoke ends of the links, especially by the longitudinal links and the spacing links 15, whether the longitudinal links are marginal links 14 or mid links 13 there is formed a staggered arrangement as is clearly indicated along the lines at or y y in Fig. 1.

Having thus described my inyention, it should he understood that there may he modifications thereof and variations therein without departing from the spirit of the inyention or exceeding the scope of the ap pended claims.
